## About

```text
At Saleshandy, I designed and owned a ClickHouse analytics pipeline for real-time email campaign metrics, reducing query latency by 70% compared with MySQL. I also designed deterministic hash-based sharding for a stateful IMAP service, scaling active connections to 10K+.

I improved Kafka processing throughput 12.5x at Saleshandy and am working on a production MCP server for Saleshandy’s outreach APIs. Independently, I built AutoReel.in, an AI video SaaS with an asynchronous job queue and distributed video rendering.
